APC 11x5.5MR-B4 Multirotor Propeller Bundle, Grey

A set of four APC multirotor propellers in 11x5.5 inch: two 11x5.5MR standard-rotation props and two 11x5.5MRP reverse-rotation props, enough for one quadcopter. APC designed the MR series for multirotors. The 11-inch diameter and 5.5-inch pitch suit larger camera and payload quads on low-to-mid KV motors.

Fit the MR props on the motors that spin in the standard direction and the MRP props on the reverse-rotation motors. A prop on the wrong motor pushes air upwards and the quad flips at take-off. On camera rigs, balance each prop before its first flight to keep vibration out of the footage.
